Progesterone replacement therapy

ABSTRACT

A hormone replacement composition, a hormone replacement dosage form, and a method of hormone replacement are disclosed and indicated for the management of hormone replacement therapy.

FIELD OF THE INVENTION

This invention pertains to a novel therapeutic composition comprising a progesterone. The invention concerns also a novel dosage form comprising a progesterone. The invention relates further to a method of progesterone replacement therapy by administering the composition, or by administering the dosage form for delivering progesterone for the indicated therapy.

BACKGROUND OF THE INVENTION

Progesterone is the active, natural progestin secreted by the ovary, mainly from the corpus luteurn, from the placenta, and from the adrenal cortex. Progesterone released during the luteal phase of the normal female cycle leads to development of a secretary endometrium. Progesterone influences the endocervical glands, and progesterone is very important for the maintenance of pregnancy as progesterone suppresses menstruation and uterine contractility. Progesterone has application in the management of ovarian disorders, in dysfunctional irregular menstrual cycles, in dysmenorrhea, in premenstrual and post menopausal symptoms, especially in the latter where menopause is an endocrine deficiency state.

The medical and pharmaceutical prior arts administered progesterone as replacement therapy to provide progesterone for the physiological and therapeutic purposes indicated above, and more specifically for postmeno-pausal hormone replacement therapy. The medical and pharmaceutical prior arts administered progesterone for these therapies by injection with progesterone supplied in vegetable oil, progesterone in a suppository for vaginal or for rectal administration, progesterone in an intrauterine or vaginal device, and progesterone in a topical cream. The prior art dispensing of progesterone in oils, suppositories and creams lacked controlled delivery, and the prior art dispensing of progesterone in an intrauterine or vaginal device frequently lead to bleeding and infection of the uterus and the vagina. The prior art has not provided an acceptable oral means for administering progesterone at a controlled dose over time, even though patients are more comfortable taking compositions and dosage forms by mouth. The properties of progesterone are reported in The Pharmacological Basis of Therapeutics, by Gilman and Rall, 8th ed, pp 1384-1412 (1990), published by Pergamon Press, Inc.

SUMMERY OF THE INVENTION

In view of the foregoing presentation, it is immediately apparent a serious need exists for an improvement in the delivery of progesterone for hormone replacement therapy. The need exists for a novel therapeutic composition comprising progesterone for replacement therapy, and the need exists for a novel dosage form comprising progesterone for replacement therapy. Accordingly, it is an object of this invention to provide a therapeutic composition comprising progesterone and it is an object of the invention to provide a dosage form comprising progesterone, which are indicated for progesterone replacement therapy. It is additionally an object of this invention to provide a novel method of administering the composition comprising the progesterone for replacement therapy, and to a novel method of administering the dosage form for administering progesterone for replacement therapy, The invention provides an improvement in the administration of progesterone in comparison with intramuscular, vaginal, intrauterine and topical administration for progesterone replacement therapy.

EXAMPLE 18

DISCLOSURE FOR USING THE INVENTION

The invention concerns a method for administering progesterone for hormone replacement therapy 10 ng to 1200 mg over a period of 30 hours. The method, in one administration comprises admitting orally into the patient 10 ng to 1200 mg of a progesterone or a progesterone active compound, that is administered from a therapeutic composition as a controlled hormone replacement dose for the intended effect.

The method concerns also a method for administering 10 ng to 1200 mg of progesterone, or a therapeutically-equivalent progesterone-like hormone, by admitting orally into the patient a dosage form comprising a semipermeable wall permeable to aqueous-biological fluid and impermeable to the passage of progesterone and hormones possessing progesterone activity, which wall surrounds a member selected from the group consisting of a capsule and a hydroxyalkylcellulose to define an internal compartment, which compartment comprises a progesterone layer and a displacement-push layer and with an exit means for delivering the progesterone from the dosage form. The dosage form delivers the progesterone by imbibing fluid through the semipermeable wall into the dosage form causing the progesterone to change from a resting state to a dispensable state, and the displacement push composition to expand and push the progesterone composition through the exit, whereby through the combined operations of the dosage form, the hormone replacement therapy is affected at a dose controlled rate over a sustained period of time.

The dosage forms of this invention provide unexpected results as seen in the accompanying FIGS. 4 and 5. FIG. 4 shows the progesterone dissolution in deionized water and various formulations. In FIG. 4, all the tablets comprise 80% progesterone and 0.5% magnesium stearate. The tablets comprising both surfactant polyoxyethylene 40 stearate and polyvinylpyrrolidone comprised 10% polyvinylpyrrolidone XL and 9.5% polyethylene 40 stearate. In additional tablets, the disintegrant polyvinylpyrrolidone and/or the surfactant polyoxyethylene 40 stearate with mannitol. The tablets weighed 125 mg and were made with a 1/4 inch (7.5 mm) tool. The tablets were tested in a USP bath with 900 ml of 37° C. artificial intestinal fluid and 50 rpm stirring, with filters used to eliminate light scattering from undissolved particles. In FIG. 4, the clear triangles indicate tablets made free of both surfactant and disintegrant; the dark triangles indicate tablets comprising surfactant and free of disintegrant; the clear circles indicates tablets comprising disintegrant and free of surfactant and the dark circles denotes tablets comprising both surfactant and disintegrant. The results of FIG. 4 show that surfactant and the disintegrant had a synergetic effect on the progesterone dissolution that is essential to the bioavailability of a hydrophobic drug like progesterone. The combined functions of the disintegrant and the surfactant is for the disintegrant to dissipate or break down the drug-layer or tablet rapidly after it is dispensed from the dosage form, and in accompanying FIG. 5, the function of the surfactant is to increase the solubility in the environment of use, a patient. The accompanying FIG. 5, depicts the solubility of progesterone in water as a function of surfactant concentration, as measured for polyoxyethylene 40 stearate at 25° C. expressed by clear squares, and at 37° C. as expressed by hatched squares.
